Think of ice floes sparkling under the sunlight. That white-blue hue has a name of its own: Alice Blue. This pale azure gem rose to fame thanks to Alice Roosevelt Longworth, Theodore Roosevelt's daughter, who took a liking to this shade and sparked a fashion craze across the States. And if that wasn't enough, it even inspired the hit song "Alice Blue Gown" in Harry Tierney's 1919 Broadway musical "Irene."

Fast forward to 1940, and the musical's film adaptation had Anna Neagle and Ray Milland basking in the Alice blue spotlight. Adding to its legacy, "AliceBlue" became one of the classic 1987 X11 colour names, proving its staying power in the fast-paced world of web design.
